EUPRAXIA was the goddess or spirit (daimona) of good conduct.
Aeschylus, Seven Against Thebes 223 ff (trans. Weir Smyth) (Greek tragedy C5th B.C.) :
"When you invoke the gods, do not be ill-advised. For Peitharkhia (Obedience) is the mother of Eupraxia (Success), wife of Soter (Salvation)--as the saying goes."
